Description

Technical Field

[0001] This utility model relates to the technical field of municipal rainwater collection equipment, specifically a municipal rainwater collection and interception treatment device. Background Technology

[0002] To facilitate rapid rainwater drainage, municipal rainwater harvesting equipment is often required. Utility model patent application CN202022048171.5 discloses a municipal rainwater harvesting system. This system collects rainwater through a storage well and uses capillary action of a suction rope to draw water from the well into the soil layer, ensuring the normal growth needs of plants and making full use of water resources. After opening the well cover, the suction rope with hooks is simultaneously pulled up, driving the trash rack to rise and remove it, allowing the accumulated garbage on the trash rack to be disposed of. The cleaning process utilizes knotted ropes to prevent the suction ropes from falling into the water storage well. The knotted ropes also maintain the stability of the debris rack, eliminating the need for additional fixing devices. According to the publicly available technical solutions, existing municipal rainwater harvesting equipment suffers from several problems. Firstly, rainwater transported through pipes is prone to blockages due to sediment settling into the pipes, hindering urban drainage efficiency. Secondly, rainwater in the wells and pipes can easily produce odors, negatively impacting the air quality above the wells.

[0003] Therefore, how to design a municipal rainwater collection and sewage treatment device has become the problem we need to solve. Utility Model Content

This utility model is reasonably designed, convenient to use, and suitable for rainwater collection and sludge interception.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal rainwater collection and interception device, comprising a well body and a well cover, wherein a rainwater collection component is installed on the well body and the well cover, the rainwater collection component includes a side pipe and a mesh, an interception component is installed at the bottom of the well body, the interception component includes an interception box and a mesh plate, water flow components are installed on both sides of the interception box, the water flow components include an upstream pipe and a downstream pipe, a movable component is installed on the inner side of the well body, the movable component includes a flap and a spring, and a limiting component is installed on the inner side of the well body, the limiting component includes a support plate and a retaining ring.

[0006] Furthermore, a support ring is integrally formed on the inner wall of the top of the well body, the four sides of the well cover are secured to the inner wall of the top of the well body, and the bottom of the well cover is secured to the top of the support ring.

[0007] Furthermore, the mesh is formed on the manhole cover, and the mesh is evenly distributed on the inner side of the manhole cover. The side pipe is welded to both sides of the manhole body, and the side pipe is connected to the top of the manhole body.

[0008] Furthermore, the top of the intercepting box is welded to the outer side of the well body, and the bottom of the well body passes through the top of the intercepting box and extends to the inner side of the intercepting box.

[0009] Furthermore, the inner side of the mesh plate is bolted to the bottom of the well body, and the outer side of the mesh plate is bolted to the inner wall of the intercepting tank. One end of the upstream pipe is welded to one side of the intercepting tank, and the downstream pipe is welded to the other side of the intercepting tank.

[0010] Furthermore, the other end of the upstream pipe passes through the intercepting box and is welded to the bottom of the well body. The upstream pipe is connected to the inside of the well body, and the downstream pipe is connected to the inside of the intercepting box. The side pipes are vertically distributed at the top of the downstream pipe.

[0011] Furthermore, one side of the flap is installed on the inner side of the well body via a pivot, the retaining ring is integrally formed on the inner side of the well body, the outer side of the flap is clamped on the inner wall of the well body, and the top of the flap is clamped on the bottom of the retaining ring.

[0013] Beneficial effects: 1. When this municipal rainwater collection and interception device is in use, rainwater falls through the mesh on the manhole cover into the inside of the manhole, or rainwater from the surrounding area is collected into the inside of the manhole through the side pipe. Then, the gravity of the rainwater pushes the flap downward, compressing the spring and causing the rainwater to flow downward into the inside of the interception box. At the same time, rainwater transported from the upstream pipe enters the inside of the manhole and flows downward into the inside of the interception box. Due to the increased cross-section of the interception box, the flow velocity slows down, and the silt and sand carried in the rainwater settles at the bottom of the interception box. The mesh filter filters out the less dense floating or suspended matter. After settling and filtration, the rainwater flows through the top of the interception box into the downstream pipe. The flow velocity of the rainwater in the downstream pipe increases, preventing silt and other substances in the rainwater from settling in the pipe, ensuring smooth pipe flow, and thus effectively ensuring the speed of rainwater drainage in the city and reducing urban flooding.

[0014] 2. When it is not raining, this municipal rainwater collection and interception device, supported by a support plate, pushes the flap upwards with a spring and presses it tightly against the bottom of the retaining ring. The top between the two flaps is sealed with a seal. When rainwater in the interception box, upstream pipe, and downstream pipe produces odors due to fermentation, the flaps, retaining ring, and seal effectively prevent the odors from drifting upwards, thus preventing the odors from drifting upwards through the manhole cover to the ground and ensuring the safety of the air environment around the manhole.

A sewage interception component is installed at the bottom of the well body 1. The sewage interception component includes a sewage interception box 5 and a mesh plate 6. Water flow components are installed on both sides of the sewage interception box 5. The water flow components include an upstream pipe 7 and a downstream pipe 8. A movable component is installed inside the well body 1. The movable component includes a flap 9 and a spring 12. A limiting component is installed inside the well body 1. The limiting component includes a support plate 11 and a retaining ring 13. A support ring is integrally formed on the inner wall of the top of the well body 1. The four sides of the well cover 2 are secured to the inner wall of the top of the well body 1. The bottom of the well cover 2 is secured to the top of the support ring. One side of the flap 9 is installed inside the well body 1 via a rotating shaft. The retaining ring... The retaining ring 13 is integrally formed on the inner side of the well body 1. The outer side of the flap 9 is clamped on the inner wall of the well body 1. The top of the flap 9 is clamped on the bottom of the retaining ring 13. The support plate 11 is welded to the inner wall of the well body 1. The support plate 11 is located at the bottom of the flap 9. The support plate 11 is connected to the bottom of the flap 9 by a spring 12. A sealing strip 10 is welded on the inner side of the well body 1. The sealing strip 10 is clamped on the top of one side of the flap 9. When it is not raining, under the support of the support plate 11, the flap 9 is pushed upward by the spring 12 and pressed tightly against the bottom of the retaining ring 13. The top between the two flaps 9 is sealed by the sealing strip 10. When the rainwater in the intercepting tank 5, the upstream pipe 7 and the downstream pipe 8 produces odor due to fermentation, the flap 9, the retaining ring 13 and the sealing strip 10 are used to effectively prevent the odor from drifting upward, thereby preventing the odor from drifting upward to the ground through the well cover 2 and ensuring the safety of the air environment around the well body 1.

[0022] In this embodiment, the mesh 4 is formed on the manhole cover 2, and the mesh 4 is evenly distributed on the inner side of the manhole cover 2. The side pipes 3 are welded to both sides of the manhole body 1, and the side pipes 3 are connected to the top of the manhole body 1. The top of the intercepting tank 5 is welded to the outer side of the manhole body 1, and the bottom of the manhole body 1 passes through the top of the intercepting tank 5 and extends to the inner side of the intercepting tank 5. The inner side of the mesh plate 6 is bolted to the bottom end of the manhole body 1, and the outer side of the mesh plate 6 is bolted to the inner wall of the intercepting tank 5. One end of the upstream pipe 7 is welded to one side of the intercepting tank 5, and the downstream pipe 8 is welded to the other side of the intercepting tank 5. The other end of the upstream pipe 7 passes through the intercepting tank 5 and is welded to the bottom end of the manhole body 1. The upstream pipe 7 is connected to the inner side of the manhole body 1, and the downstream pipe 8 is connected to the inner side of the intercepting tank 5. The side pipes 3 are vertically distributed on the top of the downstream pipe 8. In operation, rainwater falls through the mesh 4 on the manhole cover 2 into the inner side of the manhole body 1, or is collected from the surrounding area into the inner side of the manhole body 1 through the side pipe 3. The gravity of the rainwater then pushes the flap 9 downward, compressing the spring 12 and causing the rainwater to flow downward into the inner side of the intercepting tank 5. At the same time, the rainwater transported in the upstream pipe 7 enters the inner side of the manhole body 1 and flows downward into the inner side of the intercepting tank 5. Due to the increased cross-section of the intercepting tank 5, the flow rate slows down, and the silt and sand carried in the rainwater settles at the bottom of the intercepting tank 5. The smaller floating or suspended matter is filtered by the mesh plate 6. After settling and filtration, the rainwater flows through the top of the intercepting tank 5 into the downstream pipe 8. The flow rate of the rainwater in the downstream pipe 8 increases, preventing the silt and sand in the rainwater from settling in the pipe, ensuring smooth pipe flow, and thus effectively ensuring the speed of rainwater drainage in the city and reducing urban flooding.

[0023] When in use, this municipal rainwater collection and interception device allows rainwater to fall through the mesh 4 on the manhole cover 2 into the inner side of the manhole body 1, or collects surrounding rainwater into the inner side of the manhole body 1 through the side pipe 3. The weight of the rainwater then pushes the flap 9 downwards, compressing the spring 12 and causing the rainwater to flow downwards into the interception tank 5. Simultaneously, rainwater transported from the upstream pipe 7 enters the inner side of the manhole body 1 and flows downwards into the interception tank 5. Due to the increased cross-section of the interception tank 5, the flow velocity slows down, causing the sediment carried in the rainwater to settle at the bottom of the interception tank 5. The smaller floating or suspended solids are filtered out by the mesh plate 6. After settling and filtration, the rainwater flows through the top of the interception tank 5 to... Downstream pipe 8 increases the flow velocity of rainwater, preventing sediment and other debris from settling in the pipe and ensuring unobstructed flow. This effectively ensures the city's rainwater drainage speed and reduces urban flooding. When it is not raining, the flap 9 is pushed upward by spring 12 under the support of support plate 11 and pressed tightly against the bottom of retaining ring 13. The top between the two flaps 9 is sealed by seal strip 10. When rainwater in intercepting tank 5, upstream pipe 7, and downstream pipe 8 produces odors due to fermentation, the flap 9, retaining ring 13, and seal strip 10 effectively prevent the odors from drifting upwards and thus prevent the odors from drifting upwards to the ground through manhole cover 2, ensuring the safety of the air environment around manhole 1.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
